Title: Improvements in and relating to swing or like trays for the conveyors of bakery units
Inventor: WARRINGTON JAMES IRVINE DUDLEY
IPC: A21B3/07
Filed: 1954-10-23
Abstract: 783,428. Endless chain conveyers. BAKER PERKINS, Ltd. Oct. 18,1955 [Aug. 23, 1954], No. 24479/54. Class 78 (1). A tray adapted to be suspended or otherwise attached to a bakery conveyer in such manner as to hang level during travel, and of the type which is provided with rear and front guard lips 3, 6 to prevent baking pans carried on the tray floor 2 from slipping off, has its front lip 6 carried on a framework 7 pivoted to the side members 1 of the tray and biased upwardly to normally retain the lip in guard position. The bias is effected by a counterweight provided by a cross-bar 11 joining a pair of T-members 8 which form the framework 7. The short arms 9 of the T-members are pivoted to the side members 1 at 9a. The tray is suspended from a pair of chains 5 by pins 4 extending outwardly from the side members 1. A stop plate 12 associated with the lip 6 limits upward movement of the lip and co-operates with a stop 13 to limit downward movement. At the discharge station the lip is lowered by contact of a roller 14 on each member 8 with a plate 17 carried by a pivoted lever 18 which is moved towards the oncoming tray in timed relation with the movement of chains 5 by a cam 20 having a groove 22 co-operating with a follower roller 23 on the lever. Continuing movement of the chains 5 and lever 18 causes the tray to tilt, whereupon the upper edge of each side member 1 engages a follower roller 29 on one arm of a bell-crank lever 28, the other arms of the bell-crank being joined by a bar 33 which pushes against the rear of the pans carried by the tray to dislodge them. The pans then slide off the tilted tray over a bridge plate 26 carried by the lever 18 to a receiving surface 25.

Title: Improvements in or relating to electric distant control systems
IPC: G05D3/14
Filed: 1936-09-11
Abstract: 481,517. Electric control systems. STANDARD TELEPHONES & CABLES, Ltd., and BECK, A. C. Sept. 11, 1936, No. 24811. [Class 40 (i)] In a remote control system, in which variable resistance signal-transmitting and receiving devices form a bridge circuit with the line, and an out-of-balance relay across the bridge controls movement of the receiving device to balance the bridge, a resistance varying inversely with the applied voltage shunts the relay or a resistance varying directly with the voltage is connected in series with the relay. Between the sliders on the resistances, R1, R2 of the bridge Rl, R2, R3, R4, and R5 are connected a polarized relay S1 and milliammeter MA in series, shunted by metal rectifiers MR1, MR2. The slider of resistance R2 is carried on a shaft which is rotatable in either direction by the motor M1 upon the operation of one of the clutches MC1, MC2. Upon the slider of the resistance R1 being moved, the relay S1 is energized causing one of the relays S2, S3 to close the circuit of the corresponding clutch, and allows the motor M1 to rotate the shaft until balance is restored. The resistance of the rectifiers MR1 MR2 decreases with applied voltage so that a more sensitive relay and milliammeter may be used, as the maximum current through the meter and relay when the bridge is completely out of balance is reduced due to the shunt effect of the rectifiers. Preset resistances and switches, such as PR1, SW1 may be used and resistance R5 is adjustable to allow for the voltage drop along the line. If the motor switch SW2 be opened, the position of the slider on the resistance R2 may be determined by balancing the bridge by adjustment of the slider on resistance R1.

Title: New epoxide compounds
IPC: C08G59/24
Filed: 1960-07-18
Abstract: The invention comprises epoxide compounds of the formula: <FORM:0950285/C2/1> in which R1 and R2 represent methyl groups or hydrogen atoms and n=1 or 2.  The novel compounds may be made by treating a compound of the formula: <FORM:0950285/C2/2> with a dehydrohalogenating agent to convert the halohydrin group to a 1:2 epoxide group and, if desired, epoxidising the carbon-to-carbon double bond in the cyclopentene ring, in any desired order of succession.  As dehydrohalogenating agent, a strong alkali, such as sodium hydroxide or potassium hydroxide, is suitable. The double bond may be epoxidised with an organic per-acid such as peracetic, perbenzoic peradipic or monoperphthalic acid.  Alternatively, the compound may be treated with hypochlorous acid followed by strong alkali. The starting materials of formula II may be made either (1) by an additive reaction of a monohalohydrin: <FORM:0950285/C2/3> where Hal is halogen, for example bromine or chlorine, with dicyclopentadiene in the presence of an acid catalyst or of a Lewis. acid, such as sulphuric acid or boron fluoride or a boron fluoride complex; or (2) by condensing an epihalohydrin of the formula: <FORM:0950285/C2/4> with dihydrodicyclopentadiene -8- ol.  Detailed examples are given.ALSO:Curable mixtures comprise diepoxides of the formula: <FORM:0950285/C3/1> in which R1 and R2 represent methyl groups or, preferably, hydrogen atoms and n is 2 or a curing agent for epoxide compounds, e.g., an amine or amide, anilene-formaldehyde resin, urea-formaldehyde resin, melamine-formaldehyde resin, polymer of aminostyrine, polyamide, isocyanate, isothiocyanate, polyhydric phenol, phenol-aldehyde resin, oil-modified phenol-aldehyde resin, reaction product of an aluminium alcoholate or phenolate with a compound of tautomeric reaction, a Friedel-Crafts catalyst, phosphoric acid, or preferably a di- or polybasic carboxylic acid or anhydride thereof.  An accelerator such as a tertiary amine or polyhydroxy compound may also be added.  The curable mixtures may also contain a proportion of the above epoxide compounds whose epoxide groups are wholly or partially hydrolysed and as active diluents, mono-epoxides. Further polyepoxides such as mono- or polyglycidyl ethers of mono or polyalcohols or phenols, polyglycidyl esters of polycarboxylic acids, and aminopolyepoxides. Fillers, plasticisers or colouring matters may also be added, e.g., asphalt, bitumen, glass fibres, mica, quartz meal, cellulose, kaolin, silicic acid or metal powders.

Title: Improvements relating to composite aerials
IPC: H01Q5/40
Filed: 1957-08-09
Abstract: 850,974. Aerials. McCAIG, J. S. July 29, 1958 [Aug. 9, 1957], No. 25132/57. Class 40(7). A multi-band aerial system consists of two spaced support units disposed in parallel planes, one of them carrying two or more separate loop aerials each tuned for operation in separate bands and the other a like number of similar loops used as reflectors. In one embodiment the aerial system is supported by a mast 10, capable of rotation and carrying a cross-arm 11 secured in a bracket 12. At one end of the cross-arm is a casting 16 to which are fixed four bamboo canes 15 supporting three aerials 17, 18, and 19 in the form of concentric squares of conductor one wavelength long at the required operating frequencies; e.g. for the ten, fifteen and twenty metre bands. Insulators 22 inserted in the lower sides of the squares form feed points to which the feeders 21 are connected. On the opposite end of the cross-arm a similar casting 24 carries four further bambo canes 23 supporting like conductors 25, 26, 27 acting as reflectors for the three aerials. These conductors also have insulators, 29, in their lower sides and across each is provided an adjustable tuning stub 28. The ends of the stubs 28 and the feeder 21 are conveniently attached to an auxiliary cross-arm supported between a pair of insulators as shown and releasably attached to the mast at 31. The two units may be rotated about the axis of the cross-arm through 90 degrees to convert the system for use with vertically polarized signals. When this is done the auxiliary cross-arm is no longer in contact with the mast at 31. The length of the cross-arm is made about one-fifth of the mid-wavelength to be used. The aerials and reflectors may be made circular instead of square and may be any number of half wavelengths in circumference at the frequencies at which they are to be used. Directors and additional reflectors may be added.

Title: Improvements in or relating to arrangements for operating clutches
IPC: F16D25/08
Filed: 1944-12-18
Abstract: 599,807. Operating clutches. PESCO PRODUCTS CO. Dec. 18, 1944, No. 25366. Convention date, Dec. 24, 1943. [Class 80(ii)] [Also in Group XXIX] In a fluid-operated clutch having a cylinder mounted concentrically with the clutch axis and a tubular piston slidable therein under fluid pressure to cause clutch disengagement, means are provided which compensate for changes in the position of the piston due to wear of the clutch members. As shown, applied to the operation of a conventional type of friction clutch 10, Fig. 2, interconnecting driving and driven shafts 20, 32 respectively and released by movement of levers 36 acting on a presser plate 24, an annular piston 50 carrying a ball race 56 which operatively engages the levers 36 reciprocates in a fixed annular cylinder 44 formed from a base member 40 and inner and outer tubular members 38, 42 respectively. Rotary movement of the piston is prevented by a guide shoe 62 mounted thereon and co-acting with a guide rod 58 which also carries a spring 58b acting on the shoe 62 to hold the piston 50 firmly against the levers 36 at all times. Air vents 72, 76 are provided for the cylinder and for the space enclosed by a flexible boot 66 protecting the exposed working surface of the piston 50. Remote control of the clutch is effected by a pedal 13b, Fig. 3, acting through a plunger 13d on the fluid trapped in a master cylinder 13f which communicates with the clutch cylinder 44 through a power intensifier which acts purely as a fluid link until a predetermined working pressure is attained when it operates as a follow-up relay. To compensate automatically for wear in the clutch friction facings, the cylinder 44 is given such initial capacity that movement of the levers 36 and therefore of the piston 50 to the right due to such wear still allows sufficient working volume to operate the clutch, the excess fluid thus expelled from the cylinder 44 escaping into a reservoir 13a through a port 13e uncovered by the plunger 13f when the pedal 13b is retracted by a spring 13c. The reservoir 13a is initially filled to a level 13m by unscrewing a vented closure plug 13g, a check valve 130 being provided to indicate the attainment of the correct level. The Specification as open to inspection under Sect. 91 comprises also subjectmatter abridged in Group XXIX and describing the construction and operation of the power intensifier. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to unwoven textile materials
IPC: D04H1/68
Filed: 1955-09-05
Abstract: Dispersions or emulsions used, e.g. as foams, to impregnate a web of intersecting fibres to bond them together on heating contain natural and/or synthetic rubber together with a pre-or intermediate condensate of an aldehyde synthetic resin or a modification thereof having reactive groups which are capable of cross linking with reactive groups on the rubber molecules so that on heating the rubber is converted into its resilient state in which it is resistant to ageing and to dry cleaning solvents and the pre- or intermediate condensate is converted into its final insoluble state.  The weight of resin used may be greater than the weight of rubber.  Examples of suitable dispersions or emulsions are produced as follows.  (1) To a dispersion formed by adding to a butyl alcohol solution of a water-insoluble butylated urea-formaldehyde precondensate modified with an alkyd resin of adipic acid and trimethylolpropane an anion-active highly sulphonated fatty acid and a solution of casein, there is added a solution of ammonium nitrate and the resulting dispersion is mixed with a dispersion of a butadiene-acrylonitrile copolymer, a gelatine solution, and an anion-active fatty alcohol sulphonate, and the whole is stirred to form a foam.  (2) To a butyl alcohol solution of a water-insoluble butylated urea-formaldehyde precondensate there is added a dispersion of polymethylmethacrylate and to the resultant dispersion there is added a solution of polyvinyl alcohol and a dispersion of a butadiene-styrene copolymer. (3) To a solution in butyl alcohol of butylated phenol-formaldehyde precondensate there is added an anion-active fatty acid and the solution is then vigorously stirred into a casein solution, whereafter there is stirred in a dispersion of a butadiene-styrene copolymer and natural latex together with an alkyl benzene sulphonate.  (4) To an emulsion containing a butylated melamine-formaldehyde precondensate in butyl alcohol and an anionic fatty alcohol sulphonate there is added ammonium nitrate and natural latex with positively charged rubber particles.  (5) A phenol-formaldehyde precondensate is stirred into a dispersion of natural rubber and a casein solution and an alkyl naphthalene sulphonate are added.  (6) To an aqueous solution of a trimethylol-melamine precondensate and ammonium nitrate there is added with stirring a dispersion of a butadiene-styrene copolymer followed by solutions of gelatine, an alkyl benzene sulphonate and a fatty alcohol sulphonate.
